Kingda Ka
Jackson, New Jersey
Six Flags Great Adventure | On May 21, 2005 Six Flags Great Adventure introduced Kingda Ka, the tallest, fastest roller coaster on the planet to the public. This $25-million Swiss designed "rocket coaster" uses hydraulic motors to launch the trains along a horizontal section of track from zero to 128 mph in an impressive 3.5 seconds. The trains then begins a vertical ascent up a steel tower that peaks at 456 feet or 45 stories. Crossing over the apex the train enters a vertical descent plunging through a 270-degree spiral twist again reaching speeds in excess of 100 mph. One final surprise comes before the brake run, a 129-foot tall camelback hill, that offers plenty of negative G\'s also known fondly as "airtime". |
